摘要：

The effect of anodic polarization on the surface composition of Bi-Ru oxide, Bi2Ru2O7+y, electrodes in acid solution and acid-alcohol solutions has been studied by scanning electron microscopy, energy dispersive X-ray analysis, and X-ray photoelectron spectroscopy. In acidic solution the surface is unstable under either oxidation or reductive conditions, with Bi being lost from the structure. During electrolysis the surface becomes covered with particles of a Bi oxide species.
